General Notes

HCUP coding includes race and ethnicity in one data element (RACE). If the source supplied race and ethnicity in separate data elements, ethnicity takes precedence over race in setting the HCUP value for race.

Two HCUP data elements contain source-specific information about the race and ethnicity of the patient.

  • RACE_X retains information on the race of the patient as provided by the data source.
  • HISPANIC_X retains information on the Hispanic ethnicity as provided by the data source.

Not all data sources provide information on race (RACE_X) and ethnicity (HISPANIC_X).

RACE_X and HISPANIC_X are not available on the HCUP National (Nationwide) Inpatient Sample (NIS), Kids' Inpatient Database (KID), and the Nationwide Emergency Department Sample (NEDS).
